HOISTING APPARATUS.

To all whom it may concern:

Be it known that I, ALBION E. Norms, a citizen of the United States, residing at Cambridge, in the county of Middlescx and State of Massachusetts, have invented an Improvement in Hoisting Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My invention relates to hoisting apparatus and consists more particularly in improvements which add to the eliiciency and economical operation, as well as facilitating the control of such apparatus.

My invention will be best understood by reference to the following description when taken in connection with the accompanying illustration of one specific embodiment thereof, while its scope will be more particularly pointed out in the appended claims.

In the drawings :-Figure 1 shows in side elevation a hoisting tower embodying one anus; that the j'iapplication of this invention form of my invention; Fig. 2 is a sectional plan, on an enlarged scale, showing the principal controlling and motive part'sfor controlling the movements of the trolley and bucket; Fig. 3 is a side elevation of 'the'part shown in Fig. 2; Fig. 4 shows in perspective and on an enlarged'scale theconstruction and the connections of the controlling levers; Fig. 5 is a longitudinal sectional ele- :vation of the valve which governs the pressureactuated controller for the trolley drum," Fig. 6 isa sectional elevation showing the pressure controller for the trolley drum; Fig. 7 is a sectional elevation of the hand brake and controlling levers for the trolley drum; Fig. 8 is a plan view of the same; and Figs. '9 and 10 show diflerent positions for the brake controlling levers.

Referring to the drawings, I have there shown my invention as applied to a hoisting tower 1, carrying the laterally extending iples of the invention boom 2, 'whichlatter provides a'track-way for the. trolley carriage 3, by which tl1e hoisting element, herein represented as the grab or bucket 4, is carried. While I have shown my invention as embodied in an apparatus of thistype, that is, playing the instrument-antics which are lreneinspecifically described, and while this willisuflicicntly set forth thebroad princifor the understanding of those skilled in the art, it is to" be under- Specification of Letters Patent.

is not limited to this particular type of hoisting apparatus, or to a hoisting apparatus employing the elements which are here alone set forth, but that numerous other applications and embodiments of the he ein described invention may be had. Y

Referring to the specific details of the illustrate?) apparatus, the bucket 4, which maybe of any suitable or usual construction, such for example, as that set forth in U S. Patent No. 699,000, dated April 29, 1902, is provided with operating ropes by which the raising and lowering of the bucliet and the.

opening and closing of the bucketfiaws may be controlled. In the present instance the operatin ropes are two in number, and com-.

prise the hoisting rope 5, by which the bucket is suspended and raised or lowered, and the opening and closing rope .6, by which the aws are opened or closed. These ropes both pass upward over and about suitable sheaves 7 upon the trolley, thence obliquelynpward over the guide sheaves 8 near the top of the tower 1, and thence dow nwardto the operating room near the base of the tower, where they pass over and.

about and are secured to suitable rope-winding drums 9 and 10 (Fig. 2), the former, or the hoisting drum, serving to control the hoisting rope 5, and the latter, or the opening and closing drum, serving to control the openingand closing rope 6. a

The trolley with its attached bucket is traversed outwardly along the boom by meansof the trolley-rope 11 fixed to the outer end of the trolley carriage, whence itpasses to the end of the boom over the-guide.

sheaves 12, thence .back to the tower over and about the guide sheave '13, and thence to the trolley drum 14: (Fig. 2) upon which it is wound or unwound at the will of the operator. The trolley drum is driven by any suitable form of motor, but preferably by means of a steam engine or other prime ,Inover which is adapted to convert into the required mot-ion any suitable form of energy, such as pressure fluid, received from a constantly available source of supply. When the bucket is hoisted the inward pull of. thcoblique hoisting rope 5 tends to traverse the trolley inwardly along the boom toward the tower, so that the trolley may be traversed at will in either direction by.

merely winding in the trolley rope on the or releasing the trolley drum to permit tlie rope to unwind.

The clutch-operating sleem 23 carries the i to One important feature of my invention is the arrangement of controlling devices in such simple and efficient manner that the entire control or the bucket through the three rope-winding drums described, may be handled by a single operator stationed upon he platform 15 in the operating room.

Any suitable devices for driving the ropewinding drums may be employed, but referring to the details of the driving connections for the drums, which are here shown for the purpose of illustrating my invention, the hoisting drum 9 and opening and closing drum 10 are loosely journaled side by side upon the main driving shaft 16, but may be clutched thereto, either separately 7 or together by being forced into engagement with the centrally located clutch member 17 (see broken away portion, .Fig. 2). The drum shaft is connected at opposite ends through a crank and connecting-rod connection, to a two-cylinder horizontal engine, for which, however, may be substituted any suitable motor.

Any suitable clutch-operating devices may be'employed for the drums 9 and 10 and I have here indicated sliding collars 18 and clutch-operating screws 19 of the type described in my prior Reissue Patent No. 12,085, for forcing the drums either separately or together into clutching engagement with the shaft,- For this purpose the clutch screws for the drum 10 are connected through suitable connections to the operating rod 20 which is connected to be advanced or retracted by-the overhead operating'shaft 21. The clutch-operating screws for the drum 9 are connected to the rod22, which latter is connected to be moved as the sleeve 23 is turned, which sleeve is journaled for independent movement upon-the shaft 21.

arm 24 attached to the link connection 25, the latter extending to the operating platform 15, where it is attached to the hand lever 26. The clutch-operating shaft similarly has connection through the upright arm 27 and a connecting link 28 with the hand lever 29 also at the operating platform. The hand levers 26 and 29 are pivotally mounted side by side (see Fig. 4), so that through their manipulation the operator can readily control the clutching or un clutching of the rope-windingflrums. 'By

the side of the hand lever 29 is a substantially horizontal foot lever 30, (see alsoFigh fulcrumcd upon the supportin bracket 31 with the hand lever 29. The foot lever Ivvhich is :u'rang'cd'to be conveniently oper- .60"-

atcd by the tower operator is connected to a passing up and over suitable 5 leaves, leads across the tower and thence down to the vices at the .0

is also connected the spring 3% tending normally to close said throttle. The latter, however, may be readily opened to a greater or less extent through the upward pull of the throttle rope 32 caused by downward pressure upon the foot treadle 30. It will of all the movements of the bucket may be' exercised by a single operator without altering his position upon the operating platform. Although other means for winding in or letting out the trolley rope 11 may be employed, I have here provided for that purpose a prime mover in the form of an additional but. smaller double-cylinder horizontal trolley engine, connected by means of a crank and connecting rod to drive the trolley drum l4.- The latter is loosely journaled upon its driving shaft, but may be clutched to or means of the lever 35 which is adapted .to turn the nut 36 and force the drum into ven gagement with the clutch member-37 at the opposite end of the drum. The clutch mem ber 37 is keyed to the driving shaft, to which latter are also secured at opposite ends of the drum crank disks which are encircled by the automatic brakes38. The latter permit driving movement of the en gine in a direction to wind the rope on the trolley drum but prevent engine movement in the opposite direction. Any suitable brake construction may be employed for the purpose, such as that shown in my prior patent Reissue No. 12,040.-

In addition to the automatic brake or brakes 38 the trolley rope-winding drum 1% is also provided with a brake 39 encircled and engaging a suitably formed surface directly on the drum itself. This brake,'which will be more fully referred to, is of such a construction that it normally leaves the drum free to turn in the direction of wind ing on, but opposes the unwinding movement of the drum, however, may be elevated to release the brake so that the drum may also be turned to unwind thev trolley rope. The end of the brake lever 40 there being provided,

.is connected to the brake controlling-rope 41,

passing upwardly over the sheaves 42' and- 43 and thence down to suitable controlling described), to which devices are also connected a brake-'releasing-lever 40 which perating platform (to be de-= platform by the clutch-controlling-rope 44, the opposite end of which, after passing over sheaves 45 and 46. is attached to the clutch-operating lower 35 to apply or release the clutch. The starting and stopping of the trolley engine may alsolie controlled from the operating controlling the energy supply for the engine, this being accomplishedherein by means of athird controlling rope 47, which, passing over appropriatesheaves, is connected (see Figs. 2 and 3) to the throttle lever 48 of the trolley engine where it actuates a throttle placed in the engine supply pipe. Automatic brakes 49 are preferably provided upon the hoisting drum shaft for in the direction when winding on, these being similar tothe brakes provided at' opposite ends of the trolley drum shaft.

Referring now more particularly to the controlling devices at the operating platform, the trolley engine throttle rope 47 is connected (Fig. 4) to one arm of abellcrank lever 50,'the opposite arm of which is pivoted to a link 51 connected to a sliding block 52 upon the hand-lever 26, the hand latch 53 being provided to lie closely adjacent to the handle of the lever 26 and have connection to the sliding block, through the links 54, whereby the operator, without removing his hand from the lever 26, may alsoopen and close or partially close the throttle for the trolley engine by. pressing or releasing the hand latch 53. The connectiongot the throttle controlling rope 47 to the bell-crank lever; 50 being substantially inline with the axis about which the hand lever 26 is moved, movement of the latter does not tend to draw down the trolley rope, or. affect in any .way the control of the throttle therethroug'h.

.In order to control the application of. the trolley drum brake 39 and the trolley drum clutch 37, and thereby the movements of the trolley rope, I have provided a hand latch pivoted adjacent the handle of the hand lever 29. but in order that the control of such hand latch over the trolley drum may be exercised with nicety and efi'ectiveness I have interposed between such latch and the brake band a pressure-actuated controller, by which power is directly applied jointly to the brake and clutch.

Referring to Figs. 4, 5 and 6, the brake controlling ling rope 44 pass about a sheave 7 6 connected at the operating platform to the piston rod 56, the latter having attached thereto (Fig. 6) the piston 57 working Within the pressure 0 linder 58. It therefore follows that when the piston is drawn down it draws down on athe two operating ropes and simultaneously ing pulljon the. two ropes.

releases the brake and disengage-s the fr cti 0n clutch,;the sheave 7 6 placingequ'ahz-s rope 41 and the clutch controlof the cylinder is connected to the atmosphere through the vent pipe 59, but the upper part has connection to a pipe (50, which may be placed in communication with a source of steam or other pressure or with the atmosphere .atwill, by means of the hand latch 55 on the hand lever 29. The piston is normally held at the top of the cylinder by the tension of a spring at the brake, but when the hand latch 55 is moved to admit pressure through the pipe (30, the piston is forced down and'the brake released. To control the supply of pressure through the pipe 60 the hand latch has jointed connection through the link 61 with a sliding block 62, the latter attached through the link 63 to the pivoted bell-crank lever 64. The depending end of the latter (Fig. 5) is forked and embraces the headed end of. the valve stem 65 arranged in line with the axis about which the hand lever 29 turns.

The valve stem passes through suit-ably packed openings through the valve chamber 66, within which it is attached to a D-slide valve 67, adapted to slide along the valve seat 68. At the opposite side of the valve chamber the valve stem is encircled by a spiral spring 69 adapted to press against a washer and nut upon the stem,yso that the latter is normally held in the position shown with the nuts 70 abutting against the stop piece 71. Steam or other pressure is admitted to the valve chamber through the admission pipe 72. The port 73 is connected to the cylinder through the pipe 60 and the port 74 is connect d to the exhaust pipe 7 5 (see Fig. 4). In the position shown, and so long as the hand latch 55 is not gripped by the hand of the operator, the valve 67 maintains communication between the ports 73 and 74, and therefore between the cylinder 58 and" the exhaust. \Vhen the hand latch is pressed by the hand of the operator the valve 67 is moved to the left, as viewed in Fig. 5,

ing the port 73, and, therefore, the cylinder 58 to the live pressure in the valve chamber. This immediately releases the brake at the trolley drum and renders the latter eifective for let-ting out the rope, the speed of the traverse of the trolley being within the control of the attendant through variations of the hand pressure upon thetlatch 55.

The. construction of the trolley drum brake 39 possesses points of novelty and advantage, particularly as applied to this class of hoisting devices, there being obtained by control over the trolley drum.

Referring to Figs. 71() I have there shown the details and represented the action of the brake under varying conditions. Re-

ferri. particularly to-Figs. 7 and Sthe The. lower part bmk R tes 4 p s; a pair -01 Su tably:

am against the pressure of the spring 69,, openits employment a very complete and delicate row shown in Fig. 7. This places a fri(:- tional pulllupon the band, the resultant. of

shaped and spaced plates pivotallymounted at 77 upon the link 7 8, the latter being also pivotally secured for swinging movement at 79 upon the fixed support 80. The upper and lower halves of the brake band are secured at their ends to the brake lever 40, respectively at the points 81 and 82, these points being so selected both with reference to the pivotal attachment 77 of the lever to the link '78 and a center line pa ssing from the pivotal center 79 ofth-e link to the axis of the trolley drum, that the band tends to open or release the drum on tipping movement of the leuer about its v,pivotal attachment 77 (Fig; 10) or on the downward tipping movement of the link 7 8 (Fig. 9). The pull of the trolley rope normally tends to turn the drum in the direction of the arwhich will lie approximately (according to the adjustment) in the direction of the link 78, as represented in Fig. 7, tending to draw the link to the position there shown. This position of the lever and link drawsthe band about the drum preventing movement of the latter in the direction of the arrow,

. of the drum.

and, therefore, preventing unwinding of the rope. The pull of the drum is resisted by the spring 83, which latter encircles the upright rod 84: between the adjustable nuts 85 and the stirrup 86, which latter is secured to the lever 40. This spring tends to press the outer end of the lever down toward the adjustable abutting nuts 87 and maintains the necessary tension on the band; The spring 83 is adjustable by means of nuts 85 so that varying resistance may be offered to. the pull of the band, thereby regulating the load under which the brake willslip. The

rod S l is loosely secured to an underlying fixed support, so that it may rock back or forth to adapt itself to movements of the lever 40.

The link'78 has rigidly secured thereto arearwardly extending arm 88 from which depends a bolt 89, the latter carrying at its lower end adjustable nuts 90, between which and a stirrup 91, which latter is secured to the lever arm 40, is a relatively weak spring 92, but of suflicient strength to spread apart the outer ends of the lever 40 and the arm 88, thereby to sustain the link 78 and the attached ends of the band.

As stated, the brake normally assumes the'position shown in Fig. 7, preventing the unwinding of the rope, When the drum is turned in the opposite direction, however, by the trolley engine, the friction on the lower half of.the band immediately pulls the link down sufficiently toward the extreme position represented in Fig. 9 to re lease the band and permit the free rotation When it is desired to release the band for the unwinding of the rope, the

freed for rotation in the direction repre-,

sented in Fig. 9, while, at the same time, delicately controlled for rotation in the opposite direction, being capable of releas ng either gradually .or completely, so that he speed in unwinding may be sensitively con-' trolled. The clutch lever 35 (Fig. 3) is adapted to work against a spring 93, which spring, therefore, normally maintains the drum clutched to the driving shaft.

From this description of the operating levers it will readily beseen that the operator has within the control of his right hand the clutching and unclutching of the grab opening and closing rope, and, at the same time, through the hand latch 55, the control of. the inward moyement of the trolley.

Subject to the control of his left hand is the clutching and unclut-ching of the hoisting rope drum and the throttle control of the trolley engine, the throttle control of the hoisting engine being within his supervision through the medium of the foot lever 30. This places within the control of a single operator those functions which have heretofore customarily required the presence of two difl'erent attendants. ation of the tower, the trolley is normally held in the position Where it is left by the brake 39 which prevents the unwinding of the rope, the load upon the rope being partlytaken by the automatic brakes 38. When the operator desires to run the trolley out it is necessary merely to press the left-hand latch 53, thereby starting the trolley engine which winds in the trolley rope, the winding-in movement of the drum being unhindered either by the brake 39 or the automatic brake 38. When it is desired to run the trolley in it is necessary only to press the right-hand latch 55, thereby releasing the brake 39 more or less according to the speed of trolley movement desired, and, at the same time, unclutching the trolley drum from the driving shaft.

Various combinations of the automatic brake 38, the friction clutch and the brake 39 may be employed to accomplish the same general results as described. In the above During the operdescribed form of the invention the autoentire load. -On the other hand, the brake 39 might beomitted, leaving the automatic iso' is released by the brake.

brake alone to prevent the unwinding movement of the drum. Or again, with the automatic brake omitted, the clutch between the v drum and the driving shaft might be omitted, or allowed to remain permanently in engagement, the engine being permitted to run backward when the drum In the latter case, and preferably in all cases, the en; gine is provided with some form of throttle relief valve, which, when cutting ofi admission to the trolley engine cylinders also releases the pressure trapped in the cylinders, thereby not only permitting the engine to run backward but preventing it from running forward after the throttle has been closed. These and other modifications, all within the spirit of my invention will be readily understood by those skilled in the art.

While I have shown and described one form of my invention, it is to be understood that the same is not limited to the details of parts herein shown, or to the specific application of the invention described, but that extensive modifications therein may be made without departing from the spirit of the invention. v
